Life on planets around BDs was considered by
[1]} (in fact, the first directly imaged
planet orbits a brown dwarf
[2]}, [3]}. They concluded
that only more massive BDs (M\(\ge \) 30 M\(_{Jup}\) ) are likely to
sustain planets with habitable conditions on sufficiently long
time scales. Surprisingly, the idea of Gurevich that life may
thrive inside the atmospheres of a BD has also been studied by
[4]} and [5]}. They
argue that there are a few tens of W0855like objects within ten
parsecs from the Sun, and that the habitable volume in them may
be hundred times larger than on Earth-like planets.
